It’s looking less and less likely that the Hubble tension is a result of observational errors. Numerous astronomical observations have shown that the Universe is [more…]
Seven years is a long time to wait for your carrier service to deliver a package. That’s how long it’s been since NASA’s OSIRIS-REx spacecraft [more…]
Ask Clara Sousa-Silva about her research and she’ll be absolutely clear: Yes, she is looking for aliens. But she is not hunting them. “The idea [more…]
Scientists have only observed supermassive black holes one billion years after the Big Bang, but astrophysicists have now breached this barrier. Astronomical observations made in [more…]
Previously unobserved frequency changes in radio signals detected in a black hole binary system could change our understanding of black hole physics. Over a century [more…]
Using the galactic glow of dwarf galaxies, researchers investigate a hypothetical particle called an axion as a possible contender for dark matter. Since the 1930s, [more…]
A 15-year study using observed radio signals from the 67 pulsars has concluded that the entire cosmos is filled with undulating gravitational waves. Gravitational waves [more…]
A new approach to understanding gravity helps eliminate some discrepancies inherent in general relativity. General relativity, formulated by Albert Einstein in 1915, revolutionized our understanding [more…]
Scientists propose a modified cosmological model that challenges the existence of dark matter and dark energy. Our current understanding of the evolution and structure of [more…]
The composition of dark matter remains a mystery, but a new theory involving quantum tunneling may have eliminated some candidates. For decades, physicists have speculated [more…]
